The rulemaking previously titled "Airline Pricing Transparency and Other Consumer Protection Issues" has been separated into three proceedings. This final rule would address the following topics from the notice of proposed rulemaking issued on May 23, 2014: the scope of carriers required to report service quality data, reporting of mainline carriers' domestic code-share partner operations; the statutory requirement that carriers and ticket agents disclose any code-share arrangements on their web sites; undisclosed biasing by carriers and ticket agents in electronic displays of flight search results; and disclosure by ticket agents of the carriers whose tickets they sell in order to avoid having consumers mistakenly believe they are searching all possible flight options for a particular city-pair market when in fact there may be other options available. Additionally, the rulemaking would correct drafting errors and make a few clarifying changes to the Department's second Enhancing Airline Passenger Protections rule. Two other proceedings will address other provisions identified in the 2014 NPRM. See RIN 2105-AE56, Transparency of Airline Ancillary Service Fees; and RIN 2105-AE57, Enhancing Airline Passenger Protections IV. These rulemakings address unrelated matters and were separated into three proceedings to avoid the risk of any delay in finalizing one issue resulting in a delay in finalizing other issues.
